It will be understood that the entire win- Fig. 13 is a lO `these drawings, the numeral `1 indicates the.`

masonry of a building having one of our izmproved windows 1n' place therein. The

v piece 2 overlaps the side members 4 and 5,at

.frame consists ofthe top cross piece 2, sill 3' land side members 4 and 5. The, top cross Athe top, as clearly shown in Fig. 7, and is rev movably secured by means of bolts. 6. -At

4 dition,.and assembled when ready to bethe bottom, the sill 3 overlaps the side members 4 and 5, where they are likewise removably secured by bolts,as shown in Fig. 11. It will be' understood that these various partscan be shipped in a lknock-down conwalled'into the building. K s

To aidin maintair'iing the shape, in transit, ofthe side members 4 and 5, weemploy othe means shown Fig. 10.'A rlliis consists ofa Wooden strip 7 placed in the opening of the side and top members, which securely 'holds in place theflat side walls .8 and 9., and

side members.

Of course', the `wooden strip 7 is removed after the frames are walled in place, and may be used over again. The

' side members 4 and 5 are each provided which forms two channels for the guidance.

. the ..1 .T e pulleys 12 a're removably held in with a center partition 10,-'formed out of the same piece as the bodyof the sidemembers,

ofthe sash weights 11. As shown in Fig. .10, a strip of metal 89 may be easily inserted Within the center' partition 10, where it may -be either` secured by bolts or rivets, or simly forced therein. As this strip .89 projects. further within the Walls ofthe building thanl do the side members of the mainframes, it servesas a wind break, andeectlfgzlly 'pre-` vents Windor' rain-from entering the room, The presence o f this strip is optional with urchaser.

place in the top of the side members, and lie 1n brackets 13 punched out. of the sidewalls of the side members. As anl additional 1 brace for the aXle of these pulleys, we have provided a slot 14 in the partition 10. By this arran ement, we are enabled to employ a pulley o v ery large diameter, thereby reducing the friction and wear, on the cables,

and permitting of the easy operation of the sash. VOwing to the large diameter-ofthe pulleys, however, it is necessary that an inforced over thehsill.. The side .coverplates 18 and-19 arev then placed in position, and are prevented {ro-m becoming disengagedat the bottom, owing to the fact` that they rest between the upturned ends 71 of the sill' coverplate, and the end of the bead "T32,- which terminates at this point. plate 17 for thetop cross piece is nextdplaced The cover- `in position, and as its ends bear against the coverplates for the side members, it isimpossible for these side member, cove'rp'lates,

to become1 disengaged `at the top. As a means for securing the coverplate for theftop cross piece in place, we provide slide bolts 52, as clearly shown in Fig. 13, which engage .oorrespoiidingly placed holes in the .side l' coverplatesf- The bolts lie within'the groove 85 formed. within the top coverplate, which groove on the under side of the coverplate,

forms a bead and engages a channel in the top'part of the u per sash, for the purposel hereinafter described. The bolts 52 are held within 'the groove by means of retainingstrps'SG, .which are riveted or otherwisel secured to the top coverplate. A slot of the vdesired length isv provided beneath these i bolts in, the coverplate of the top cross piece,

through which a nail or other suitable instrument may be inserted to L,engage a hole in the bolts, by which means they can beoperated.

From the.- above, yit Willbe -seen that the moved, after 4,which the Acoverplates for the` y side members may be taken out, which, in.

, turn, permits the removal of the coverplate for the"v sill. The above arrangement is'. adapted especiallyffo'r use twhen a shade roller is employed and where it is necessary vthat the -upperecoverplate shall, be quickly emovable to permit access to the roller. Where it is not dsiq'ed to use a shade roller,'.` Lhowever, the coverplate for the top crossV piece may have its'ends 75 out square orv sta-ight, and adapted to rest on'the tops of side.oo verplates. In this event, the side eoverplates would be put in lace last" and removed first', and anyfsuitab e means may be employed for securingv thelside cover'-` plates to he top ooverplates.

.The side coverplates .18 and 19 are each provided withthree grooves', pressed to the desired shape. The inner groove 20 acts as a guide for tlie lower` sash, While the groovesv` 21'and 22.are guides fqr the upper sash and screen' respectively. t The screen is shown at' 22a as made of metal, but it :s l v will' be understood that the 130 screen and its guiding grooves need not al- "provide the brass strip 23,*which conforms to the shape of both the upper and lower A sash ide grooves, and is securely held in place y rivets 24, or may be soldered there- 1n. The sash consists o'' outer strips 25 and inner strips 26, between which is interposed .the U-shaped frame 27, preferably made of channel iron, as clearly shown in Fig. 2. This U-,shaped piece 27 is constructed of one piece. and continues entirelyaround r p three sides of the frame.

The inner and outer frames 25 and 26 are i secured to the U-shapedframe 27, by means of rivets28, 'extending entirely through the three members. By this construction, a channel isprovided between the inner and outer frames and 26, into which glass may be slid from the top. To securely hold the glass in place', a removable bar 29, preferably -25 of channel formin cross section, is employed,

. which closes the opening at the top, between the side frames 25 and 26, and liesy upon the ends ofthe U-shaped frame 27, over apping the.l same, forv the pur os'e hereinafter described.' The 'removab e' bar 29 may conveniently be held in place bybolts passing lthrough itl and. the side frames,r as clearly i shown inzFig. 18. i l

'i Where it is desired to use more than one "glass ina single frame, we provide a muntin v consisting'of the center piece 30 (which lies .wby rivets) and side plates 31, which oyerlapbetween the inner and outer frames 25 and 26 at the top and bottom, where it is secured this center piece 30 and are riveted thereto'l l Itwillbe observed. that the Ul-shaped frame 27 llies inwardly, and is removed from the outer edges of the side frames 25 and 26 f on three sides, thereby forming a channel on or bottom portion vof the U-shapedfraine is removed from the lower edges of the frames the three sides of the frame. The horizontal 25 and 26, to form a channel into which the bead or edge piece 32 of the sill rojects to form a tight Joint,` The outer face of the bead 32 is disposedin a vertical plane, so as toilie flat against the inner face of the frame 25, making it practically impossible for water towork its way up through between the` p parts.

The removable piece 29, at the uper ed e of the top sash, is likewise removed om t e outer ed esof the frames -25 and 26,

'forming a channe the .object of which is .to

provide.' a weather proof joint between the top'eross piece coverplate 17 and the upper .L sasl1,in;as niueh as the b`ead 33 lies within tlu's'channelwhen the sash is closed'. As a further protection against the weather,

i i n spring brass strips S11-are provided within the top channel of the upper sash and the bottom channel ofthe lower sash.

The brass weather strip within the bottom channel of the lower sash, is held in place by means of the bar 87, and lies between this bar 87 and bottom of U-shapedframe 27.

`The bar S7 is removably held in place by screws 8S, and projects beyond the side frames 25 and 26, for the purpose .hereinafter described. At thetop of the upper A sash, the weather strip is removably held between the removable 'bar 29 and one of the frames 25 or 26. Wheninserting the weather strip for the bottom sash, it is angular in cross section, one end of the angle lying between the bar 87 and bottom of U-shaped frame, 'while the other rests against either the frame25 or 26, as desired. After the bar 87 is secured in place, the weather strip is then bent over thestrip 87, as shown in Figs. l and 15, the free end of which bears against thejbead 32. The weather strip for the to sash, however, can be placed in position a ter having first been formed to the desired sha e, or it may be inserted in la flat form, an after secured inplace between the removable bar. 29r and either of the side frames 25 or 26, can then be bent to shape.

The -lower cross piece of the inner sash frame 26 has its upper edge 61 turned over, as illustrated Figs. 'land 15, the object being to provld'e a continuous handle, by

'which meansdthe lower sash can easily be raised, thereby eliiinatlng the expense-and time of attaching se arate handles. The presence of thishand e, which extends the ength of the lower bar, terminating at the `inner edges ofthe vertical members of the lower sash, as shown in Fig. 17, also tends to strengthen and stiil'en the frame, particularly when the frame 1s of great width.

An important feature-in the construction of the sash, lies in the method employed of 1securing the side frames 25 and 26 to the U- shaped frame at tl1e corners;" It will l;e ol:- served that the bottom piece 92, of. the side frames .25 and .26, embraces the edges of the side pieces 90 and 94, the purl ose of which being to enable the placing` of oth rivets 91 and 91u (one on veither side of the corner formed'by the U-shaped frame) in the bottom ieee, as shown in Fig. 17, thereby great y increasing the strength of these cor` ners and insuring a right-angular frame.'

`The channels at the` sides of the sash, formed by the inner and outer frames 25 and 26` and U-shaped frame 27, contain theI removable guides 35. .These removable guides consist of metallic strips preferably V-shaped in cross section, as shown in Fig. 9, and are 'preferably made of pressed' steel. `rlo forni a non-corrosive bearing surface, we envelop these pressed steel guides with a thin sheet of@ Amaintain a tight'joint. These guide strips of the pressedsteel guides. i They, however,

continue around the open end of these steel' guides, as clearly shown in Fig."9, and bear" against the U-shapedrame 27. A=weather tight join-t is eifectually "madeby means of these non-corrosive coverings'forthe guide strips, owing to the fact. that' they bear against the 4Ushaped frame 27, which forces '.theminto the guide grooves ofthe coverplates .for thefside members 4 and 5 of: the

main frame. 4The tension of the spring brass strips v36, however, is' not 'severe enough to causetoo'much frlctlon between lthe-bearing surfaces, and therefore,the sash can .be operated with perfect ease and'still are heldin place between the'extending ends or" the removable bar 29 and the weather strip retaining piece 87, which project suli-l eiently beyond the U-shaped frame for th1s purpose. In both ends of the removable` ar 29, holesare provided, through which I the ropes orA cablesffor the weightsfextend,

and are knotted or otherwise securedl f When it is desired vto remove the sash, the

'1 bar 29 isirst removed, and is permittedto rest against theV top Acoverplate.`

Should it also be desired to remove the coverplates, the' same 'operation must lirst be performed, as'

above 'i escribed for the removal 'of the sash.'

The slide-bolts 52 are thenv disengaged from thev holes in the side coverplates, which per? mits the removalu of the top coveA late. The'side and sill coverplates can theni e re- Irnoved inthe mannerbefore described.` t

For serving as finishing strips to .the m-an frame, we'secure the VI noldin strips-4Q tothe inner and outerwalls uof t eside and to members of the main frame. These mol ing strips are preferably made of sheet metal, bent to any vdesirediorm, and. are rem-'ovably held to the'side members of the main frame by means of' tongues 41, rojecting at l intervals along the strlp 40, W ich tongues engage correspondingly spaced .slots in fthc sideV members of the main frame, and when in place, the tongue 41 can'bebent over on the insidev of the sidemembers of the main frame, whichsecurely holds th' a in, plac'e. The molding strips 40. also serve to form a weather tight joint between the side meinbers of the main frame"and the -coverplates, f

as clearly shown in Fig. `:9. These moldin strips 40 howevere maybe entirel-yoifitte if so desird- I Suitable meetingrails are 'provided be# tween the upper and lower sash tofpresent aweather tight joint.' -In'this instance; we

i `have forme .thenivof the same piece as the the lower barv of the upper sash of the framev upper bar o the lower sash side frame 26 and 25, as shown in Fig. 18. They consist .of

similar reverselyarranged portions 25a and 268t overlapping each other whenthe lsash' are closed. As these portions 25a and 26a' entering'tlre-poc be ofafnysuita are of thesame piece as theupper and lower tively, itfisonly necessary to bend them toy the desired shape, eliminating the presence of b olts or rivets to secure these meeting rails, and greatlyincreasing the strength andV rigidity o these particular mernbers, espe-- Acial'lyshouldthe s ash beof great width. T o

rails, we employ spring brass weather strips "95 and Q5-a, soldered o'r-otherwise securedto the-meeting rails on their-outerl` sides, ,--As they are bent'. around the edge ofr said meeting rails, as shown in Fig. 18, and their loose ends permittedto bear against each othern 'when the sash are closed, a positively ti ht 'members of the top and bottom sash respecinsure .apositive 'joint between these meeting joint is obtained at., a redcedc'st an a small amount of labor.

Referring to Figs. 1 and 12, it will be seen that- We -providea' spring roller curtain -.or. i

screen 55, secured by any'sui'table means to the inside of theV top 4cross piece coverplat'e V17. A slot is provided through vthe covern 'plate 17,beneath the spring roller curtain,'

through which the curtain 1s guided.. The

In present sheet metal window frame and sashconstruction, itis necessary`to use very thin sheet metal, (usually #24 gage) which is-e'asily dented and perforated, and quickly i damaged bycorrosion," In our -improved cannot be damaged after the building is'A erected, and are also protectedl by the cover-A scratched-or otherwise marred.

however', of thel main frame, we prefer tol construction, it is possible to use heavy sheetmetaL as all of the members ofthe main frame are of simple form and easily pressed The side members,

make of a thinner 'sheet metal than thecoverplates, asthese are entirely walled in and plates. While the building is inprocess of erection, the cover-plates-are not placedin position, as before stated, owing4 to the fact that` they are highly finished, and 'may be This, therefor eleaves the sill 13 unprotected before the sill coverplate -is put on, and the projecting edges maybe-bent out of shape.v To remedy this', however, concrete or `other like mixturemay be filled inthe grooves jand also 4beneath the sill in the channel 44.

.All of the bearing surfaces "are madelof sheet brass spring metal strips, or other rustproof` material, suchgas thes'trips23 3ft, 36,

25a and 126y and can be readilyrenewed` Whenevernecessary, ,and therefore, the window 1s made very durable and 'can always be -kept weather tight.

' We are aware that our con'struction'canibe 'variedwithout departing from the essence of our invention; thus, other means of balancing the sash may be employed,` or one sash be" arranged to balance the other, in which event weights and weight channels would be dispensed with, andl still the feature of the removable coverplates `(which really'constiy tute` the, finished parts of the frame) be retained, and we wish to claim this -feature of the removablefinished,parts of the frame ,broadly. Again, the' screen maybe hinged toswi'ng out instead'of sliding in grooves in Lthe slde vcoverplates l l It is' evident that lour construction of window frames may be used with the side, top

and bottom members riveted orwelded toetherthus dispensing with the knock down feature, and it may. in some cases be preferred not toremove the cover plates while f the frame is 'being Walled in, still this would not evade our invention, as the construction and arrangement of parts, which effect Aother'advantages would not be changed. :Thefeature of removability of the cover plates, however, vis one .of special importance.

H eretofore it has been necessary, in both wood and metal constructions, to wall in the completedl window 'frame and thereafter 70 paint or otherwise finish the exposed parts. l In our construction the exposed' or finishing parts` are a separate part of the window frame, and these are/ finished, painted, ja,-

panned or enameled, preferablyl at the factory, and then in their finished state are quickly'and removably secured in place and tol the previously walled in outer. frame. This not only avoids the danger of injury to the finish by the masons in walling in the V frames, but enables us to impart to the eX- posedor finishing parts the high finish desirable for-residences and office buildings,

secured by enamelingl or japanninglwhich can only be done at t efactory lor l1 e place 85 equipped with ovens or kilns.

From the foreeomg, it will be seen`that we have invented a method of eonstructlng metallic windows, radically different 'than 'those heretofore used, and whichenablesthey 9 0 production of 4metallic windows that are simple, compact, strong, durable, ornamental, rustfproof, its essential parts readily detachable and accessible for renewing or refinishing, and which, although hig lyl fini ished and ornamental. as to its exposed parts, permits of being Walled in, without `damage to said finished parts7 and all of these features and advantages areuobtained in the mostinexpensiveand practical'way ossible. 100

The sliding sash windowsofmetalic construction heretofore used, havebeen unsatisfactory `and impractical, vfand although there is an urgent demand for-metallic windows for office and residence buildings, we believe our method to'y bezthe first that-will beacceptable to architects, andwill be generally adopted, and we therefore wish) our invention and claims 'to be Hbroadly con'4 strued, as' we consider our invention on'e of 110 value and importance.
